Interesting detail: I saw this link in an email I got very recently about VimConf. At the bottom it says "Copyright 30 Cubits LLC"—the contact email at 30 Cubits' page[1] is for Joey, I'd assume it's the same Joey as the guy behind VimConf. Man's on a roll!
Actually, I assumed that VimConf was a great marketing strategy for castingcode.tv - am I wrong to think that the product came first and then the conference idea?
